LASTING-PINCEBS.

Specification of Letters Patent.

Patented Aug. 31, 11915.

Application filed November 21, 1913. Serial No. 802,241.

To all whom it may concern Be it known that we, WALDO HUoK and ALFRED W. HUCK, citizens of the United States, residing at Kansas City, in the county of Jackson and State of Missouri,

and useful Improvements in Lasting-Pincers; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to lasting pincers, and more particularly to a device of this character comprising pincer jaws and a hammer, the principal object of the invention being to provide a jaw structure, wherein a toothed plate may be removably seated in the working face of the jaw, so as to hold securely when in place, but adapted for quick and easy removal, so that the jaw plate may be replaced when it has become worn.

It is also an object of the invention to provide one of the jaws with a removable hammer, and also to provide improved details of structure for both the jaws and the hammer parts.

In accomplishing these objects we have provided the improved details of structure hereinafter described, and illustrated in the accompanying drawings, wherein Figure I is a perspective view of a lasting pincer constructed according to our invention. Fig. II is a side elevation of the pincer jaw showing in dotted lines the apertures through which a tool may be projected to spring the jaw plates from their seats. Fig. III is an enlarged longitudinal section of the pincer jaw and hammer, illustrating the improved hammer mounting. Fig. IV is a plan view of one of the jaws, illustrating its dove-tail mounting. Fig. V is a plan view of the jaw plate taken alone. Fig. VI is a perspective view of the plate. Fig. VII isfii cross-section on the line VII-VII, Fig. I

Referring more in detail to the parts 1 designates the pincer jaws, which, in so far as the mounting of the removable plates is concerned, are identical in constructlon so that but one need be described in detail. In the face of the jaw 1 is a longitudinal groove 2 having cross-groove 3 at its inner end, and a seat 4 at its outer end, the seat being formed by removing metal from the face of the jaw at the side of the extended plane of the groove 2. The sides of the groove 2 are parallel, and are parallel with the sides of the jaws, but are undercut to form a dovetail socket.

6 designates a jaw plate which is adapted for application to the pincer jaw and is curved to conform to the curvature thereof, one end of the plate having laterally projected arms adapted to fit within the cross slots 3, and the opposite end being provided with a head 8, adapted to seat within the seat 4; the head 8 and a part of the shank 9 which connects the head with the arm -7, being toothed, and a part of the toothed portion of the shank being provided with downwardly beveled flanges 10, which are adapted to project into the dovetail slot 2 of the jaw member. The jaw is also provided with an aperture 12, through which a tool may be projected to force the inner end of the plate out of its seat and thereby loosen the plate so that it may be removed.

The hammer which we prefer to use in combination with the jaws, comprises an ordinary head 14 having a screw threaded socket 15 for receiving the thread d head 16 of an attaching shank. The head 16 is reduced to form a tapered shoulder 17, and attaching shank 18, which are adapted to bear against the countersunk shoulder 19, in the outer face of the jaw 1, and thread into a socket 20, respectively. The hammer head is provided with a transverse screw threaded aperture 22, which intersects the main socket so that a screw 23 may be projected therethrough to contact with the head 16 and hold the hammer in an adjusted position. The screw head 16 is preferably provided with a longitudinal seat 24 for receiving the end of the screw 23, so that the latter may be tightened against the screw head without injuring the threads thereof.

In using a device of this construction, the jaws may be .provided with the removable plates so that they may be used in the ordinary manner, the fact that the plates are removable and may be manufactured separate from the jaws or the pincer bodies,

making it possible to case-harden the plates and thereby insure a longer life therefor.

When the plates have become worn, or should they becomebroken, they may be easily and quickly removed from the jaws and new plates inserted, the dove tail connection between the plates and jaws insur ing proper connection therebetween, and the parallel facing of the plate edges and jaw parts not only facilitating the removal and application of the plates, but also reducing the cost of manufacture. The hammer is applied to the under jaw of the pincer by screwing the shank 18 into the socket 20 until the shoulder 17 seats snugly within the countersink in the under-face of the jaw. The hammer is then threaded onto the shank until the proper adjustment is secured and is then fixed in position by tightening the screw 23 against the seat on the screw head, this adjustment insuring a rigid removable combination between hammer and pincer, and at the same time providing for ready adjustment of the hammer to shit individual users.

Having thus described our invention,

what we claim as new therein, and desire to secure by Letters-Patent, is

1. In a lasting incer, a jaw having a longitudinal .doveail slot provided with parallel edges and having a cross-groove and head at opposite ends and a plate having a shank provided with dove-tailed flanges adapted for seating within the dovetailed groove, and having cross-arms and a head at opposite ends for fitting within the cross-groove and seat, substantially as set forth.

2. A lasting pincer comprising a jaw having a dove-tailed slot and having a seat at the outer end of the slot, and a jaw plate having a head adapted for application to the seat and a shank for projection through the slot, the portion of the shank adjacent the head being provided with laterally directed dove-tailed flanges and the remaining portion being plain to pass freely through the slot opening, for the purpose set forth.

3. A lasting pincer comprising a jaw having a screw threaded socket and a countersunk seat, a screw comprising integral shank and head portions, and a beveled connecting neck adapted to seat in the countersunk seat; the head portion of the screw having a longitudinal seat forming a flat bearing face for aset screw, a hammer having a threaded socket adapted for receiving thescrew head, and a set screw extending through the hammer and adapted for seating in the seat in said screw head.

.In testimony whereof we afiix our signatures in presence of two witnesses.
